Created page with " == Android build == First, download and install Android NDK r25c or later by unpacking release taken from the Android developer site [https://developer.android.com/ndk/down..."

New page

== Android build ==

First, download and install Android NDK r25c or later by unpacking release
taken from the Android developer site [https://developer.android.com/ndk/downloads].

To be used, only enviroment variables need to be properly set, as in example:

export PATH="$PATH:/opt/android-ndk"
export ANDROID_NDK=/opt/android-ndk
export ANDROID_NDK_HOME=/opt/android-ndk

Since there is no precompiled SDL2 for Android we need to prepare that as well.
First is to download latest from SDL github [https://github.com/libsdl-org/SDL/releases/latest].
In time of writing version was SDL2-2.26.3, but later version should work fine as well.

Next step is to build SDL2 with Android NDK and prepare include files in required form.

tar xvfz SDL2-2.26.3.tar.gz
cd SDL2-2.26.3

To compile for ARM64 (arm64-v8a):

cmake -S . -B build_arm64 \
-DANDROID_PLATFORM=android-24 \
-DANDROID_ABI=arm64-v8a \
-DCMAKE_INSTALL_PREFIX=~/SDL_Android_arm64 \
-DCMAKE_TOOLCHAIN_FILE="$ANDROID_NDK_HOME/build/cmake/android.toolchain.cmake" \
-DSDL_SHARED=ON -DSDL_STATIC=ON -DSDL_STATIC_PIC=ON -DSDL_TEST=ON \
-DSDL2_DISABLE_SDL2MAIN=OFF -DSDL2_DISABLE_INSTALL=OFF \
-DCMAKE_INSTALL_INCLUDEDIR=include -DCMAKE_INSTALL_LIBDIR=lib -DCMAKE_BUILD_TYPE=Release

make -C build_arm64 install

To compile for Intel x86:

cmake -S . -B build_x86 \
-DANDROID_PLATFORM=android-24 \
-DANDROID_ABI=x86 \
-DCMAKE_INSTALL_PREFIX=~/SDL_Android_x86 \
-DCMAKE_TOOLCHAIN_FILE="$ANDROID_NDK_HOME/build/cmake/android.toolchain.cmake" \
-DSDL_SHARED=ON -DSDL_STATIC=ON -DSDL_STATIC_PIC=ON -DSDL_TEST=ON \
-DSDL2_DISABLE_SDL2MAIN=OFF -DSDL2_DISABLE_INSTALL=OFF \
-DCMAKE_INSTALL_INCLUDEDIR=include -DCMAKE_INSTALL_LIBDIR=lib -DCMAKE_BUILD_TYPE=Release

make -C build_x86 install

To compile for Intel x86_64:

cmake -S . -B build_x86_64 \
-DANDROID_PLATFORM=android-24 \
-DANDROID_ABI=armeabi-v7a \
-DCMAKE_INSTALL_PREFIX=~/SDL_Android_x86_64 \
-DCMAKE_TOOLCHAIN_FILE="$ANDROID_NDK_HOME/build/cmake/android.toolchain.cmake" \
-DSDL_SHARED=ON -DSDL_STATIC=ON -DSDL_STATIC_PIC=ON -DSDL_TEST=ON \
-DSDL2_DISABLE_SDL2MAIN=OFF -DSDL2_DISABLE_INSTALL=OFF \
-DCMAKE_INSTALL_INCLUDEDIR=include -DCMAKE_INSTALL_LIBDIR=lib -DCMAKE_BUILD_TYPE=Release

make -C build_x86_64 install

To compile for ARM (armeabi-v7a):

cmake -S . -B build_arm \
-DANDROID_PLATFORM=android-24 \
-DANDROID_ABI=armeabi-v7a \
-DCMAKE_INSTALL_PREFIX=~/SDL_Android_arm \
-DCMAKE_TOOLCHAIN_FILE="$ANDROID_NDK_HOME/build/cmake/android.toolchain.cmake" \
-DSDL_SHARED=ON -DSDL_STATIC=ON -DSDL_STATIC_PIC=ON -DSDL_TEST=ON \
-DSDL2_DISABLE_SDL2MAIN=OFF -DSDL2_DISABLE_INSTALL=OFF \
-DCMAKE_INSTALL_INCLUDEDIR=include -DCMAKE_INSTALL_LIBDIR=lib -DCMAKE_BUILD_TYPE=Release

make -C build_arm install

After this all is ready for MAME to be built. Note that it can be built for android-arm,
android-arm64, android-x86 and android-x64. If you are testing with emulator you only need
android-x86 build, but for real device nowdays android-arm64 will only be needed, and there
are less and less android-arm.

make SUBTARGET=tiny SDL_INSTALL_ROOT=~/SDL_Android_x86 android-x86 -j9

This prepared binaries, but still we need to deploy application to device.
Easiest way is to use Android Studio [https://developer.android.com/studio].

All build features are also available using gradle, next set of commands will
create debug build and deploy it on connected Android device.

gradlew assembleDebug
gradlew installDebug
